his invention r'ellites to improvements in rol ,eil beiriigs. Y My present inventlonl'elates pztrtiouhtrly to iiiiproteinents in the roller berihg of the 'eliss shown in the U. S. Letters Patent No. 89:2;41'65 dated July T, 1908, to the ztpp'lient nld Charles, lll'. Deke, 1nd is n modifiention, and in son-1e respe'et-sliin improvement upon the struc'tliie there illustrated and described.

lie mitin objects of Vthis invention are: First, t'o provide zin improved roller bearing in which the bering i'olle'rs :ire retained without the use df Cages or journal pins or the iollers.- S'eeond, to provide :in improved roller bering;V in which the piti-ts ie Simp e und co'noiniel in structure and eiisily nis-- senibld or diszissembled. Third, to provide iii improved roller b'ering'r which is so oonstructd and arranged that the ivenr and t'i'i'cti'oll on the parts' is minimized.

Further objects, and objects relating to structurel details will definitely tippen-r from the detailed desoription to follow.

I icomplish the objects of my invention by the devices ind means described in the following speoiention.

The structure described constitutes one eiteetive embodiment of my invention. Other embodiments would bev readily devised by those skilled in the art.

The invention is clearly defined und pointed out in the olaims.

A structure constitutingr :1n effective and preferred 'embodiment of the features of my invention clearly illustrated in the neoompanying drawing. forming n' part of this specification. in which: l

Figure lv is n' detail side elevation-ot one of my improved bearings, the hub und the outer bearing' member being shown in longitudinal sections', the other parts being shown teken on a line corresponding to' line 2 2 of Fig. l, the hub being omitted. Fig. 3 is an enlarged detail longitxulinnl section tuken on :x line (rol-respondinter to lino fl-'3 ot Fin'.

Fig. 2 is u transverse sectionl l, the hub being omitted, the axle and the bearing rollers being shoivn in full lines.

In the drztwin'g,siiiiili reference hr- :ietel-n refettn nil-nini pn'rtn thronghout the seteral, vie/tts, find the sectional views tire taken looking in the. dingen-en of sie um@ nr'roits ut the ends' of the section lines.

Referring to the drawing, l'represents a shaft or an tixlesuch as the :title bf 2L ve hiere. The innen banning member e in adapted to re'oeiv'e the iztl, The biiter tient'- ing member 3 is arranged ih the h'ut s 4 of the Vehicle Wheel oipu'lley. These beii'ring members are preferably o'oilicl ns illtistrate'd. The be'i'ings re ordinetrily rrng'ed in pairs, the other bearing, being a 'substantiel duplice-te of the bearing illustrotted, ns their arrangement will be obvious to' those skilled in the nrt te which this invention reltit'es.

The bearing rollers 5 |arepreferably 'ooni'el as shown, the sides being' of uniform taper from end 'to end, the small `ends 6 being` ooniettl 'find their lrg'e ends being 'conveited. The inner bearingfmniber 2 is provided With :in outwardly-preieating thrust flange at its large end. his flange is preferably shouldered to' form :in annular seat 8 for the dust excluding ring;r 9. A ringlike thrust bearing member 10 is preferably provided for the. large ends of the rollers. This thrust bearing member is sleeved upon the inner bearing' member .2 to rest ngninst the flange 7. The bearing: face 11 ot the thrust ring or thrust bearing member l() is preferably curved in cross section, theeurvnture of the thrust ring being somewht less thnnthat of the convexed ends of the rollers. This is indicated by the dotted lines in Fig. 3.

The rollersl are retained in lplace when the outer bearing member is removed b'y the retainingr ring 12. which is sleeved uponthe inner bearing member and provided with un annular groove 13 in its inner face into whichv the ooni'enl ends of the rollers projeet."

ing ring 13 is looked in position by men-ns fit-the looking ring 14. the inner bearing member being provided with :i `groove 15 to receive the saine. The inner bearing member is shouldered at 16 to form a seat for the retaining rin 12. This provides an effective means for etachably securing the parts together so that they can b e readily `assembled or disassembled as occasionniay require. Theretaining ring is so' arranged that its outer edge engages'the conical ends of t-he rollers, but, as previously stated, the parts are normall out of contact.

By thus arranging the parts the. necessity` for cages or journals for the rollers is obviated, as the rollers are 'entirely free to travel about the bearing and impinge with each other and -ivith' the cones throughout the entire lengthofthe rollers. Further, the thrust ring or bearing member and the retaining ring are both loosel 'secured to the inner bearing cone so that sliould the rollers, for any reason become out of alinement, they are readily brou ht into. alinenient by the shifting of the rings. Another very great advantage is that when the outer boxing or cone is removed, the rollers can be very easily shifted about to permit a. thorough cleaning of the cone and the rollers if desired, Without the removing of the rollers, however, the structure is so very readily assembled or disassembled that the.

rollers can be released-merely by the -slippiilgv olf of the retaining ring.

` formi'n whicliiI have embo ied the same and I indthis -formtobe highly satisfactory. I

Vsu erior structure.

'being' con-vexed, the parts are notflikely to. `lcut out. and' the wear is minimized.
